city. I should think you would feel obligatedââ
Holmes scowled. âI am obligated to no one.â
âPray do not misunderstand meââ
âIâm sorry, my dear Watson, but you should know me well enough to assume my total indifference towards such a case.â
âAt the risk of appearing more dense than most of my neighboursââ
âConsider! When given a choice, have I not always sought out problems of an intellectual character? Have I not always been drawn to adversaries of stature? Jack the Ripper, indeed! What possible challenge could this demented oaf present? A slavering cretin roaming the streets after dark, striking at random.â
âHe has baffled the London Police.â
âI venture to suggest that that may reflect the shortcomings of Scotland Yard rather than any particular cleverness on the part of the Ripper.â
âBut stillââ
âThe thing will end soon enough. I daresay that one of these nights Lestrade will trip over the Ripper while the maniac is in the process of committing a murder, and thus bring him triumphantly to book.â
Holmes was chronically annoyed with Scotland Yard for not measuring up to his own stern efficiency; for all his genius, he could be childishly obstinate on such occasions. But further comment from me was cut off by the ringing of the downstairs bell. There was a slight delay; then we heard Mrs. Hudson ascending, and it was with astonishment that I observed her entrance. She was carrying a brown paper parcel and a pail of water, and she wore an expression of sheer fright.
Holmes burst out laughing for the second time that morning. âItâs quite all right, Mrs. Hudson. The package appears harmless enough. Iâm sure we shall not need the water.â
Mrs. Hudson breathed a sigh of relief. âIf you say so, Mr. Holmes. But since that last experience, I was taking no chances.â
âAnd your alertness is to be commended,â said Holmes, as he took the parcel. After his long-suffering landlady left, he added, âJust recently, Mrs. Hudson brought me a parcel. It was in connection with an unpleasant little affair I brought to a satisfactory conclusion, and it was sent by a vengeful gentleman who under-estimated the keenness of my hearing. The ticking of the mechanism was quite audible to me, and I called for a pail of water. The incident gave Mrs. Hudson a turn from which she has still not recovered.â
âI donât wonder!â
âBut what have we here? Hmmm. Approximately fifteen inches by six. Four inches thick. Neatly wrapped in ordinary brown paper. Post-mark, Whitechapel. The name and address written by a woman, I should hazard, who seldom puts pen to paper.â
âThat seems quite likely, from the clumsy scrawl. And that is certainly done in a womanâs hand.â
âThen we agree, Watson. Excellent! Shall we delve deeper?â
âBy all means!â
The arrival of the parcel had aroused his interest, not to mention mine; his deep-set grey eyes grew bright when he removed the wrappings and drew forth a flat leather case. He held it up for my inspection. âWell, now. What do you make of this, Watson?â
âIt is a surgeonâs instrument-case.â
âAnd who would be better qualified to know? Would you not say also that it is expensive?â
âYes. The leather is of superb quality. And the workmanship is exquisite.â
Holmes set the case upon the table. He opened it, and we fell silent. It was a standard set of instruments, each fitting snugly into its appropriate niche in the crimson-velvet lining of the case. One niche was empty.
âWhich instrument is missing, Watson?â
âThe large scalpel.â
âThe post-mortem knife,â said Holmes, nodding and whipping out his lens. âAnd now, what does this case tell us?â As he examined the case and its contents closely, he went on. âTo
